SHUTTLE-ACTUAIING MECHANISM FOR LOOKS.

Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed August 27, 1917, Serial No. 188,266. Renewed February14, 1921. Serial No. 445,014.

To all whom it may concern:

Be it known that I, RICHARD HAT'I'ERSLEY SMITH, a subject of the King ofGreat Britain, and resident of Keighley, in the county of York, England,have invented a certain new and useful Improvement in Shuttle-Act-uating Mechanism for Looms, of which the following description,having reference to the accompanying sheets of drawings, is aspecification.

It relates to the arrangement and construction of the several devicesforming the picking or shuttle actuating mechanism for looms of the typeknown as overpick picking mechanism and has for its object theproduction of said several devices of such-a character as will enable meto secure the benefits and advantages of the over-pick picking mechanismas to its functions, ease of actuation and the like; in conjunction withchange box mechanism of the rising and falling type having the bindersmounted at the front of the series of compartments of the shuttle box,thus said benefits and advantages are secured while further securingothers by enabling the weaver more readily to manipulate the shuttle andattend to the replenishing of the weft or to carry out other desiredadjustments which are permitted by making use of shuttle boxes havin thebinders at the front.

In order that my said invention may be readily understood I havehereunto appended sheets of drawings illustrative thereof to which byfigures and letters reference is made in the following description.

Figure 1 is a sectional end elevation of sufficient of a loom toillustrate the application of my improved parts.

Fig. 2 is a sectional front elevation taken on line A. B. of-Fig. 1 andas seen from the front of the loom.

Fig. 3 is a sectional front elevation of certain parts at the end of theloom to the left, illustrating the positions of my devices ashereinafter described.

C indicates the slay board of the loom, D the end frame of said loom andE the layswords, F a rotary shaft in said loom, G the picking cam and Hthe arm actuated by the said picking cam.

In carrying my invention into effect I arrange the shuttle boxes 2 sothat the series of compartments have the binders 8 at the front of saidshuttle boxes and toward the front of the loom, while the pickers 4 andtheir picker spindles 5, together with their guiding bars 6 are at theback of said shuttle boxes thus the picking strap 7, connecting a picker4 to the picking stick 8, extends from the rear of the shuttle box tosaid picking stick by which arrangement the whole front of the shuttlebox is left free and easy of access for the weaver.

The picking shafts 9 which are of the vertical type are arranged to beat an angle to the vertical plane taken longitudinally through the loom,as well as being inclined to the vertical plane taken crosswise saidloom, so that as the oscillations of said shaft 9 and the parts that itcarries are in such a direction or follow such a path as to cause thepicking stick 8 to move from a lower position at the outer end of theslayboard to a higher as it is picking or throwing the shuttle andmoving toward the interior of the loom, its directlon of motion is suchthat it holds the picking strap 7 at all times in a stretched conditionfrom the time that said picking stick 8 commences to move until it isfinally arrested at the extreme end of its path of motion and thatnotwithstanding the motions of the slay-board C.

Although I have hereinbefore described the arrangement of the pickingshaft 9 in the inclined position as illustrated, as being used in a loomhaving multiple shuttle boxes it is obvious that I may make use of saidarrangement of the picking shafts 9 in connection with single shuttlelooms wherein advantages would accrue by making the picking stick followthe path of motion described.

Such being the nature and object of my said invention what I claim is 1.In shuttle actuating mechanism for a loom, a rotary shaft, a picking cammounted.

on said shaft, a picking shaft arranged at an angle to the verticalplane, an arm carried by said shaft to be actuated by the picking cam,another arm fixed upon said shaft and extending approximately at rightangles therefrom, a picking strap fixed upon said arm, a pickerconnected to said strap, guiding devices upon which said picker mayslide and a shuttle box within which said picker operates.

2. In shuttle actuating mechanism for a 100m, a rotary shaft, a pickingcam picking shaft at approximately right angles mounted on said shaft, apicking shaft arthereto, a picker, a strap secured to said ranged at anangle to the vertical plane in arm and to said picker, supports andguides 10 which the rotary shaft of the loom is situfor said picker anda shuttle box Within ated and also at an angle to the vertical whichsaid picker operates.

plane in which the end frame of said 100111 is situated, an armextending from said RICHARD HATTERSLEY SMITH.
